It is a practical choice where operators need more productivity than a light pneumatic pick but do not require the mass of a 39–42 kg breaker.\u003c\/p\u003e\n\u003ch2\u003eAir Supply and Tooling\u003c\/h2\u003e\n\u003cp\u003eUse approximately 0.5 MPa as the preliminary working-pressure reference and allow for roughly 23–28 L\/s air demand depending on the supplied version and operating condition.
